请参阅图1-图3，图1-图3分别示出了本发明其中一实施例提供的雾化器100在一个方向的立体示意图、剖面示意图及一个视角的分解示意图。雾化器100包括壳体10，及位于壳体10内部的第一密封件20、多孔体30、支撑架40及第二密封件50。壳体10内储存有可雾化的液体基质，第一密封件20及第二密封件50用于密封壳体10内的液体基质，防止液体泄漏出雾化器100；多孔体30用于吸取液体基质并对液体基质加热雾化从而产生可供用户吸食的气溶胶。
壳体10包括面壳11及底座12，面壳11及底座12通过可拆卸连接方式连接，可拆卸连接方式可以为常用的方式，本实施例中采用卡扣的方式进行连接，面壳11及底座12连接形成壳体10。面壳11具有相对的近端及远端，底座12在远端处与面壳11可拆卸连接，近端处设有出气孔111，多孔体30加热雾化产生的气溶胶可从出气孔111逸出雾化器100，以便用户吸食。底座12设有供外界空气进入雾化器100的进气管121，用户在使用雾化器100抽吸时，外界空气可通过进气管121进入雾化器100，并把雾化产生的气溶胶带走从出气孔111中逸出。底座12上还设有与电源机构连接的电极122，电源机构通过电极122可给雾化器100提供电能，以便雾化器100能对液体基质加热使其雾化。
面壳11内部形成有连通出气孔111的导气管112，多孔体30加热雾化液体基质产生的气溶胶可从通过导气管112传输至出气孔111中。请继续参阅图4，图4示出了底座12在一个方向的立体示意图。底座12设有卡槽123，卡槽123用于和支撑架40卡扣连接，以将支撑架40固定于壳体10的内部。
请继续参阅图5及图6，同时结合参阅图2，图5及图6分别示出了第一密封件20在两个不同方向的立体示意图。第一密封件20为柔性材质，例如 可以为硅胶、橡胶或乳胶等材质。第一密封件20环绕于面壳11的内壁并与面壳11的内壁过盈抵接，从而第一密封件20与面壳11的内壁共同界定形成储存液体基质的储液腔13。
第一密封件20包括端面21及自端面21朝底座12方向延伸的延伸壁22，端面21及延伸壁22界定形成一收容腔室23，底座12至少一部分收容至收容腔室23中并与第一密封件20过盈配合。第一密封件20的端面21朝收容储液腔13的方向延伸有第一抵接部211及第二抵接部212，第一抵接部及第二抵接部212相对设置，且第一抵接部211及第二抵接部212之间界定形成有抵持空之间，多孔体30位于该抵持空间并与第一抵接部211及第二抵接部212相互抵接，从而使得多孔体30在水平方向上固定。
进一步的，第一密封件20的端面21上开设有供雾化后的气溶胶通过的第一开口223，第一开口223位于第一抵接部211及第二抵接部212之间的抵持空间内，多孔体30的至少一部分横跨第一开口223并与第一抵接部211及第二抵接部212抵接。第一密封件20的端面21上还设有环绕第一开口223的凸筋224，多孔体30横跨在第一密封件20端面21的部分对凸筋224提供挤压。
进一步的，为了将多孔体30在垂直方向上保持固定，请继续参阅图7，图7示出了支撑架40在一个方向的立体示意图。支撑架40包括基部41，基部41形成有与多孔体30表面形状适配的保持空间411，保持空间411用于容纳多孔体30的一部分，以使多孔体30被保持在该保持空间411中，进而使多孔体30在垂直方向上固定。基部41朝出气孔111方向延伸有套接孔412，套接孔412套接于导气管112的外壁并与导气管112流体连通，以使液体基质被加热雾化产生的气溶胶能从支撑架40中流向导气管112中。基部41朝向底座12的方向延伸有与底座12适配卡接的卡扣部413，卡扣部413与卡槽123适配卡接，从而使得支撑架40固定于壳体10内。
同时，支撑架40固定于壳体10内时，至少一部分是支撑在第一密封件20的端面21上的，且支撑在第一密封件20的这部分同时对凸筋224的剩余部分提供挤压，如图8所示。基于此，支撑架40和多孔体30共同完成在凸筋224的周向上提供挤压，由于凸筋224直接由第一密封件20形成，因此凸筋224具有一定的弹性，当支撑架40和多孔体30对凸筋224提供挤压力时， 凸筋224产生形变并在形变恢复力作用下对支撑架40和多孔体30产生反向挤压力，进而与支撑件40和多孔体30之间形成过盈配合，通过该过盈配合可密封支撑架40和多孔体30与第一密封件20的端面21之间的装配间隙，防止储液腔13的液体基质通过支撑架40和多孔体30与第一密封件20之间的装配间隙流向第一开口223，并通过第一开口223流至进气管121处，从而泄漏出雾化器100，影响用户的使用体验。
进一步为了完全密封储液腔13的液体基质，防止液体基质从支撑架40与多孔体30之间的装配间隙中泄漏，并通过支撑架40的套接孔412留置导气管112中，进而由导气管112流至出气孔111处从而可能被用户吸食，给用户带来不好的使用体验，支撑架40及多孔体30之间还设有第二密封件50，第二密封件50用于密封支撑架40与多孔体30之间的装配间隙。
进一步参见图9，图9示出了多孔体30在一个方向的立体示意图。多孔体30至少一部分浸润在储液腔13中，可由多孔陶瓷、多孔玻璃陶瓷或者多孔玻璃等刚性毛细结构制成，其内部具有微孔结构，液体基质可通过该微孔结构渗透至多孔体30中。多孔体30包括基体31，基体31具有沿雾化器100的宽度方向延伸的相对端面，该相对的端面即为多孔体30的吸液面32，吸液面32浸润在储液腔13中，因此储液腔13中的液体基质可直接通过吸液面32渗透至多孔体30中。吸液面32分别与第一密封件20的第一抵接部211及第二抵接部212抵接，从而使得多孔体30在水平方向固定。
基体31还包括延伸于两个相对设置的吸液面32之间的弧面33，弧面33和支撑架40的保持空间411形状适配，以使多孔体30保持在支撑架40的保持空间411内。多孔体30包括位于背离上述弧面33的一侧的雾化面34，雾化面34设置有加热元件35，加热元件35与底座12的电极122连接以获得电源机构的提供电能进行发热。液体基质通过吸液面32渗透至多孔体30后，可继续通过多孔体30的微孔结构渗透至雾化面34处，并被雾化面34的加热元件35加热雾化，从而产生气溶胶。
加热元件35在一些实施例中可采用不锈钢、镍铬合金、铁铬铝合金、金属钛等材质。加热元件35优选采用通过具有导电性的原材料粉末与印刷助剂混合成浆料后按照一定的轨迹形状打印、印刷、沉积、喷涂在雾化面34上之后烧结固化形成的，从而使其全部或绝大部分都与雾化面34紧密结合，具有 雾化效率高、热量损失少、防干烧或大大的减少干烧等效果。或者在其他的实施中，可以采用片状的材料蚀刻或者切削形成图案化之后粘结于雾化面34上。
进一步的，为便于对多孔体30进行保持，多孔体30还包括插接部36，插接部36自多孔体30的基体31朝底座12的方向延伸而出，雾化面34位于插接部36上，多孔体30横跨第一开口223时，插接部36插入至第一开口223中并且插接部36的两个端面与第一开口223的孔壁过盈配合，过盈配合使得多孔体30进一步保持在位。
为使雾化后的气溶胶能够通过第一开口223，多孔体30横跨第一开口223的区段与第一开口223的孔边保持有一定的空隙，具体的，多孔体30横跨第一开口223的区段位于第一开口223的中间部位，从而使得多孔体30的前后两个侧边与第一开口223的孔壁保持有第一空隙37及第二空隙38，如图10所示。此时外界空气可通过第一空隙37及第二空隙38将液体基质被加热雾化后产生气溶胶携带进入至支撑架40中，并由支撑架40进入导气管112中，进而由出气孔111排出雾化器100供用户抽吸。
需要说明的是，第一空隙37及第二空隙38优选的布置成截面寸尺寸大小是基本相同的，该布置方式对气溶胶流通至出气孔111处的速度是有利的。当然，在本发明其他实施例中，第一空隙37及第二空隙38尺寸大小也可以不相同，只需要使得气溶胶能通过第一开口223即可。
容易理解，在本发明其他实施例中，多孔体30横跨第一开口223的区段与第一开口223的孔壁也可只需形成一个空隙，只要在纵向上多孔体30没有全部遮挡第一开口223即可，此时气溶胶即可通过该间隙流通至出气孔111处。本发明实施例设置成第一空隙37及第二空隙38，可以使雾化后的气溶胶通过第一空隙37及第二空隙38分流进入导气管112中，减小气溶胶的滞留，增加吸食口感。
应当理解，在本发明其他实施例中，多孔体30也可以不包括插接部36，如图11所示。多孔体30的雾化面34基本上是沿水平地横跨第一开口223，雾化面34靠近多孔体30两端的一部分是搭接在密封元件上，雾化面34的中间部分是被悬置在第一开口223的开口端。但无论多孔体30是否包含插接部36，设置在多孔体30上的加热元件35都是处于雾化面34横跨第一开口223 的该部分上，以便加热元件35加热液体基质释放的气溶胶能充分被外部空气带走。或者，多孔体30的雾化面34是凹陷于多孔体30中的，此时雾化面34与多孔体30之间保持有一定间隙，雾化面34是朝向第一开口223的。
进一步的，请继续参阅图4同时结合参阅图13，底座12包括底壁127及自底壁127纵向延伸的侧壁128，底壁127及侧壁128界定形成底座12的容置腔室129，底座12还设有纵向延伸于容置腔室129的第一支撑板124及第二支撑板125，第一支撑板124和第二支撑板125分别对第一密封件20提供支撑，进而对多孔体30提供支撑，以使多孔体30稳固的支撑在第一密封件20上。第一支撑板124和第二支撑板125分别与容置腔室129的内壁连接，进而将容置腔室129划分成第一腔室1241、第二腔室1242和第三腔室1251，多孔体30的雾化面34位于第二腔室1242中，从而在雾化面34上雾化产生的气溶胶即可释放至第二腔室1242中，也就是说第二腔室1242为雾化器100的雾化腔室，第一腔室1241和第三腔室1251分别位于雾化腔室1242的两侧，进气管121延伸于雾化腔室1242中。因此雾化器100气流通道如图12中R1虚线所示的路径，图12示出了雾化器100在意另一个方向的剖面示意图。当用户使用雾化器100抽吸时，雾化器100内部负压，外部空气通过进气管121进入至雾化腔室1242中，在雾化腔室1242中与加热雾化释放至雾化腔室1242的气溶胶混合，并携带气溶胶通过第二空隙38进入至支撑架40中，并通过支撑架40的套接孔412进入导气管112中，再经过导气管112流动至出气孔111处排出雾化器100。
进一步的，如图13所示，第一支撑板124和第二支撑板125至少一者设有通孔126，进而使得第一腔室1241和/或第三腔室1251通过通孔126与雾化腔室1242流体连通。雾化腔室1242通常会存在高温的气溶胶，气溶胶冷凝后产生冷凝液堆积在雾化腔室1242的底部，而雾化器100的使用时间越长，产生堆积的冷凝液就越多，从而可能超过进气管121的延伸长度，进而从冷凝液通过进气管121泄漏出雾化器100。而通过在第一支撑板124和第二支撑板125的至少一者设有通孔126，雾化腔室1242中堆积的冷凝液即可通过第通孔126流至第一腔室1241和/或第三腔室1251中，从而扩大冷凝液的储存空间，有效防止冷凝液通过进气管121泄漏。容易理解，通孔126与雾化腔室1242底壁之间的间距是小于进气管121的纵向延伸长度的，以便雾化腔室 1242堆积的冷凝液及时流至第一腔室1241和/或第三腔室1251中，而不会从进气管121中泄漏。
进一步的，随着储液腔13中液体的消耗，储液腔13内液位下降，气压降低并产生负压，在负压作用下雾化器100易出现供液不畅的问题，为缓解储液腔13内产生负压，雾化器100还设有和外部空气连通的换气通道，以向储液腔13内补充空气，缓解储液腔13内的负压。
具体的，请继续参阅图14和图15，图14和图15分别示出了本发明另一实施例提供的第一密封件20和底座12在一个方向的立体示意图。在第一密封件20的第一开口223附近相对的开设两个第二开口225，两个第二开口225分布在第一开口223的两侧，第二开口225的尺寸小于第一开口223的尺寸。底座12的第一腔室1241和第三腔室1251内轴向延伸有延伸部1243，延伸部1243结合在第一腔室1241的内壁，延伸部1243朝第一密封件20方向轴向延伸并分别贯穿两个第二开口225，从而在延伸部1243与第二开口225孔壁之间界定形成换气通道。
进一步，为在延伸部1243与第二开口225的孔壁之间形成空气通道，可在延伸部1243的表面上开设纵向延伸的凹槽12431，凹槽12431与第二开口225的孔壁之间即可界定形成空气通道；或者不在延伸部1243的表面上开设凹槽12431，而在第二开口225的孔壁上开设纵向延伸的凹槽2251，此时凹槽2251与延伸部1243的表面界定形成该空气通道；或者在延伸部1243与第二开口225之间预留一定的间隙，利用该间隙也可界定形成空气通道。值得说明的是，凹槽12431的尺寸是非常小的，凹槽12431沿径向方向延伸的深度d1及宽度d2均不超过0.2mm，优选的，本实施例中深度d1和宽度d2均为0.15mm，深度d1和宽度d2不超过0.2mm可以有效地避免空间过大引起与液体基质的过量渗漏，见图16所示的第二开口225的放大示意图。
从而用户抽吸时，随着液体基质的消耗，外部空气通过进气管121进入至雾化腔室1242中，一部分空气将雾产生的气溶胶沿着气流路径R1携带至出气孔111处；另一部分空气通过通孔126进入至第一腔室1241和第三腔室1251中，并从延伸部1243与第二开口225之间界定形成的空气通道中进入储液腔13，从而为储液腔13补充空气，缓解储液腔13中的负压。容易理解，也可以在第一腔室1241或第三腔室1251其中一个腔室中设置延伸部1243， 此时对应的也至需要设置一个第二开口225，只需要在延伸部1243及第二开口225之间形成换气通道即可。
请继续参阅图17，同时结合参阅图2及图4，图17示出了电极122在一个方向的立体示意图。电极122包括电源机构连接端1221、加热元件连接端1223及连接电源机构连接端1221和加热元件连接端1223的连接部1222。电源机构连接端1221被构造沿横向方向延伸，连接部1222被构造成沿纵向方向延伸，加热元件连接端1223被构成朝加热元件35的方向倾斜延伸。具体的，在实际生产装配过程中，可通过金属嵌件注塑的方式将电源机构连接端1221沿横向方向嵌入在底座12的底壁127中，而将连接部1222沿纵向方向嵌入在第一支撑板124和第二支撑板125中，而加热元件电连接端1223则倾斜的伸入至雾化腔室124中并与加热元件35进行抵接。容易理解，电极122通常包括正电极和负电极，其中一个电极122嵌入在第一支撑板124中，另一个电极122嵌入在第二支撑板125中。
容易理解，电源机构连接端1221嵌入在底壁127中是需要暴露出来的，以便与电源机构进行电连接。而加热元件连接端1223是具有形变能力的弹片制作的，其与加热元件35抵接时在挤压力作用下容易产生形变，而在形变恢复力作用下则会更加紧密的与加热元件35接触，有效保证电性的接触良好。
需要说明的是，连接部1222中设置有横向贯穿连接部1222的过孔12221，本实施例中设置过孔12221主要是为了用来形成通孔126，由于通过126设置在第一支撑板124或第二支撑板125上，通孔126在模具上不好制作，而在电极122上设置过孔12221即可通过金属嵌件注塑方式便可形成通孔126。
综上，本发明实施例提供的雾化器100，由第一密封，20与壳体10的内壁界定形成储存液体基质的储液腔13，第一密封件20上开设有供气溶胶通过的第一开口223，多孔体30横跨于第一开口223并支撑在第一密封件20上，雾化后产生的气溶胶即可通过第一开口223流至雾化器的出气孔111处，从而可使雾化器100整体零部件较少，结构简单，装配方便。
本发明实施例还提供了一种电子雾化装置，电子雾化装置包括电源机构及上述实施例所述的雾化器100，电源机构包括电芯(图未示)、控制器(图未示)、气流传感器(图未示)及连接端子(图未示)，连接端子用于和雾化器100的电极122进行电连接，气流传感器用于感应雾化器100的进气气流， 并将感应信号发送给控制器，控制器控制电芯通过连接端子向雾化器100提供电能，雾化器100的加热元件35获得电能之后即开始对液体基质进行加热雾化产生气溶胶。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；在本发明的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本发明的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
